Columbia Rock Bridge High School has named Jason Callaham as the new head coach of its boys varsity lacrosse team.

Callaham, 22, replaces Jared Diamond, who led the Bruins to a 2-12 record last season.

A native of Chesterfield, Mo., Callaham is a 2004 graduate of Parkway Central High, where he played four seasons on the varsity lacrosse team as a middie from 2001 to 2004, he said. Callaham was an assistant coach at Rock Bridge the past three seasons, and this will be his first varsity head coaching job.

"I'm excited about it," Callaham said. "We've got a lot of guys who want to play lacrosse, and it's going to be a lot of fun this season."
